I tried a 68030 with 16mb Z3 memory and on boot I got a red screen with ‘Expansion Board Diagnostic’ and it said ‘Board Number 2’ ‘Product 3’ was defective.

JIT also doesn’t work properly. According to TomB (who implemented JIT into the Pandora port), JIT is only useful when using CPU speed “Fastest”, but if you do this then a lot of Games/Demos end up having crackling sound and also slower video. I couldn’t see any difference when I turned JIT off. Also when leaving a WHDLoad Game/Demo and go back to ClassicWB you can hear a fast repeating sound that lasts a few seconds.

So to sum up, when JIT is on I get worse performance.

Tested on Raspberry Pi 2 with RetroPie v3.2.1. I also updated UAE4Arm from ‘Source’.

So confirmed, JIT and Z3 memory do not work properly on RetroPie RPi 2.
